Tối ưu truy vấn LIKE trong hệ thống tìm kiếm: Khi kết hợp tìm kiếm vector với bộ lọc từ khóa (LIKE '%...%'), hiệu suất thường tụt dốc do phải quét toàn bộ dữ liệu. Milvus đã thử nghiệm chỉ mục N-gram để giải quyết vấn đề này—chuyển đổi truy vấn chuỗi con thành tìm kiếm theo chỉ mục đảo, giúp tăng tốc 80–190×. Thử nghiệm trên 100K tài liệu và 1M bản ghi cho thấy thời gian truy vấn giảm từ hàng trăm ms xuống còn ~1ms.
